We are living in an age of transnational development and major changes in transportation, communication, leisure activities, and work environments. For centuries, and in some places still, the accumulation of land and the enslavement or employment of farm laborers has ensured wealth. In many places this was supplanted by the ownership of factories and the employment of manual labor, or the ownership and exploitation of non-renewable raw materials such as oil, coal, and precious metals. But today the richest man in the United States is not the owner of a large ranch or a railroad, or of vast reserves of petroleum. He is Bill Gates, the owner of a computer software company called Microsoft. One of the United States’ largest exports is entertainment “software” — films, television, recordings, and computer software. Ideas are big, big business, and even U.S. foreign policy is influenced by considerations of intellectual property.
